What the Ryokan Business Act says: the 'simple lodging' category
The Ryokan Business Act (hotel law of 1948, reformed June 2018) defines three regimes: ryokan/hotel business, kan'i shukusho, and boarding-house business. Kan'i shukusho (literally 'simple lodging') covers facilities where sleeping space is shared: guesthouses, hostels, dorms, capsule hotels. It is a licence (kyoka) issued through the public health center, not a mere notification like minpaku. Its two decisive advantages: no cap on nights (365/year versus 180 for minpaku), and no minimum room count. That is why the overwhelming majority of Japanese guesthouses operate under this status.
What to look for: existing licence vs. new application, inuki (居抜き) takeover
Two routes: buy a property already licensed as kan'i shukusho (簡易宿所, 365 nights/yr) or create the licence yourself. Since the December 13, 2023 reform of the Hotel Business Act (旅館業法 (ryokan gyōhō)), a business transfer (事業譲渡 (jigyō jōto)) lets the buyer inherit the existing licence through prior prefectural approval (承継承認 (shōkei shōnin)): no more mandatory re-application. Target inuki (居抜き) takeovers (walls, furniture, licence and booking history) on Rakumachi, Tranbi or HOME'S: immediate start, verifiable revenue. Check zoning (用途地域 (yōto chiiki)) first: the licence is impossible in exclusive residential zones (低層・中高層住居専用, 田園住居) and industrial zones (工業・工業専用).
Floor area, sanitation, front desk: the hard requirements
Floor area: 33 m² minimum, relaxed since April 2016 to 3.3 m² × capacity if you host 10 guests or fewer, a 40 m² machiya can thus sleep 6-8 people. Sanitation: 'sufficient' toilets and washbasins, bath or shower required (some local ordinances set exact ratios). A physical front desk (genkan choba) has not been mandatory since 2018 if an equivalent system exists (video/ICT check-in verifying guest identity), and a manager can respond within ~10 minutes in an emergency. Always check the local ordinance: some cities still impose 33 m² or a physical counter.
Fire code (消防法 (shōbōhō)): the make-or-break cost item
A kan'i shukusho is classified (5)-i under the fire code: automatic fire alarm mandatory whatever the size (a wireless 'small facility' version is allowed under 300 m²), illuminated exit-guidance lights (yudoto), commercial fire commercial extinguishers from 150 m² (local ordinances may lower this) (150 m² depending on configuration), flame-retardant certified curtains and carpets. Budget roughly ¥300,000 of equipment for a detached house. The fire department inspection yields the Fire Code Compliance Certificate (shobo horei tekigo tsuchisho), a document the health center requires: no certificate, no licence. Cost this item before buying the property, never after.
Zoning (用途地域 (yōto chiiki)) and the health-center procedure
Under the Building Standards Act a kan'i shukusho counts as a 'hotel/ryokan': allowed in commercial, neighborhood-commercial, quasi-residential, category-2 residential, category-1 residential (≤ 3,000 m²) and quasi-industrial zones; banned in the four exclusive residential zones (low-rise and mid/high-rise) and industrial zones, unlike minpaku, which works almost everywhere. Check the zoning before signing. Procedure: pre-consultation with health center, fire department and planning office, application file (drawings, fire compliance certificate), on-site inspection, licence ~1 month after a complete filing, 2 to 4 months in practice. Fee: ≈¥52,000 in Kyoto (¥22,000–35,000 elsewhere); under 200 m², no formal change-of-use filing (threshold raised in 2019).
Kyoto vs. Osaka vs. Tokyo: three very different regimes
Kyoto is the strictest: minpaku is capped at ~60 days (Jan 15–Mar 16) in residential zones, so the kan'i shukusho licence is THE route, with a manager reachable within 800 m / 10 minutes on foot (max 5 facilities per person) and a special regime for certified machiya. Osaka: tokku minpaku (2-night minimum, 365 days/yr) closes to new applications on May 29, 2026; go through the Hotel Business Act instead. Tokyo: ward-by-ward overlay rules (上乗せ規制); commercial zones are simplest. Everywhere, minpaku owned by a non-resident requires a registered management company (住宅宿泊管理業者 (jūtaku shukuhaku kanri gyōsha)).
Realistic 2025 economics: ADR, occupancy, yield
2025 was a record year: 42.7M visitors, hotel ADR +10.8%, RevPAR +15% over nine months, occupancy +3.2 points. In Kyoto, hotel occupancy runs around 80% annually, peaking at 85–88%. A typical guesthouse: dorm beds ¥3,000–5,000, private rooms ¥8,000–15,000, realistic occupancy 65–80% in tourist cities. On a ¥40–60M machiya (cash purchase, fees ≤6%), 8–12 well-run rooms can target a double-digit gross yield, provided you budget OTA commissions (~15%), cleaning and management (15–20% of revenue).
Step by step, A to Z (3–6 months)
1) Targeting and checks: zoning (用途地域 (yōto chiiki)), hazard map, 検査済証 (kensazumishō), licence validity. 2) Pre-consultation with the health office (保健所 (hokensho)) and fire department (消防署 (shōbōsho)) BEFORE signing. 3) Purchase: offer, disclosure (重要事項説明 (jūyō jikō setsumei)), deed, fees ≤6%, cash if non-resident. 4) Licence takeover via 承継承認 (business transfer) or a new application (2–3 months). 5) Compliance works + obtaining the 消防法 (shōbōhō)令適合通知書 (shōbō hōrei tekigō tsūchisho). 6) Opening; after a takeover, authorities inspect at least once within 6 months. Allow 3–6 months from offer to first guest.
